Backing Up Bootloader and Home Directories Over the Network

ackups that are robust and resistant to disasters like fire should be distributed. Backing up by writing to external drives is good, but it is not sufficient. Here is how I back up my main machine. Backup is quick in a smaller number of rather large files (not too large as some file systems cannot cope with those), so one trick goes like this:

this is then scp‘d or rsync‘d over to another box based on a wildcard or directory like

/media/backupdrive/`date +%Y-%m-%d`

This leaves a stack of backups in case the latest one is already ‘contaminated’. rsync of the original files, uncompressed and untarred, can be fast except for the first time, but for a stack of backups it’s not suitable.

But more files need to be backed up, depending on the bootloader for instance.
